Texas Instruments · Voltage Reference · SOT-23-5
REF3430SQDBVRQ1 from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | Test pin per the datasheet, which says it should be connected from 0 V to 18 V; it is not a no-connect pin despite its name. |
| 2 | GND | power_in | Ground reference connection for the reference. |
| 3 | IN | power_in | Input supply voltage connection; the recommended supply is VOUT + VDO up to 12 V, and the absolute maximum rating is -0.3 V to 13 V. |
| 4 | OUT | output | Voltage reference output connection, rated for ±10 mA output current with an 18 mA typical short-circuit limit. |
| 5 | NIC | unconnected | No internal connection. |
